Cost basis for ETH is stuck at £2,618.95. Had a balance of 0.00000073 ETH. Purchased £300 ETH with fiat (and this is correctly reflected in the Transactions page) but the cost basis in the Dashboard is £444. Made another purchase for £185 with a similarly inflated cost/unit on the Dashboard, although reports correctly on the Transactions page. Gains/Losses on the Dashboard completely off.
